The initial 5000 miles were decent, compared to big name tyres like the Pirellis and Michelin, but a further 500 miles and my opinions of this brand took a severe nosedive. They started cracking at the inner sidewalls, after just the 5,500 miles in a little over 21 months. Sure the S6 (4K, 5.2L) is a heavy car with decent torque and power, and I do push it occasionally; but no way should this happen. Other midrange brands I use like Yokohama and Vredestein do not self destruct like this after 2 years.
They were ok, and seemed pretty good value, and though they never got those "bulges" like the ones you get in most Chinese tyres, I'm probably not going to go cross country in these UHPs anytime soon.
Maybe I'll stick to the more reputable brands, and only use these Indonesian tyres for things like low powered (and light) Chinese cars like the new MG models.
